Context: The traditional balance of power in the region has collapsed following the appearance of the Sorcerer King, Ainz Ooal Gown.
The Sorcerer Kingdom of Ainz Ooal Gown: Established recently with its capital at E-Rantel (formerly a Re-Estize fortress city). It is a nation where the living and the undead co-exist. The undead serve as tireless labourers, guards, and civil servants.
The Baharuth Empire: Formerly a rival to the Re-Estize Kingdom, it has now formally requested to become a vassal state of the Sorcerer Kingdom. Its ruler, the "Bloody Emperor" Jircniv Rune Farlord El-Nix, maintains internal autonomy but yields to the Sorcerer King in all external matters.
The Re-Estize Kingdom: In a state of terminal decline. Following a catastrophic military defeat at the Katze Plains, where tens of thousands were slaughtered by a single spell, the nation suffers from famine and political fracturing. The "Noble Faction" and "Royal Faction" are at each other's throats, while the nation’s infrastructure crumbles.
The Roble Holy Kingdom: Recently liberated from the "Demon Emperor Jaldabaoth." The northern half of the country is in ruins; the southern half remains wary and isolated. A new religious movement praising the Sorcerer King’s "strength as justice" is spreading rapidly among the commoners, led by Neia Baraja.
